When Captain John Hoyte first became a BAe 146 pilot in 1989 he put his extreme exhaustion and chronic fatigue down to the anti-social hours as he was flying permanent nights. At first he assumed this was normal.
Gradually he began to notice other symptoms
Bright lights would "jump around" and he found it hard to focus, his speech was sometimes slurred, and he had difficulty with memory and thought processing. The overall effect was of being permanently intoxicated, but without the alcohol.
Time to stop
By 2004 he was feeling very unwell and his symptoms were increasingly affecting his off-duty life. Many pilots have to’ face the day’ when they are unable to continue to fly - both for their own sake and out of a duty to their passengers.
Back to flying
Capt Hoyte reluctantly returned to flying, but like many other pilots, only part time in an effort to limit his chronic fatigue and ongoing neurological symptoms. Once again he elected not to fly in June 2005. This was to be his last flight in a BAe 146.
Captain Hoyte was finally grounded in February 2006 by a specialist Doctor who diagnosed ‘Chronic stress’, again with no mention whatsoever of contaminated air.
In April 2006 Capt Hoyte was one of the 27 Balpa pilots tested by University College London (UCL) – all of whom were found to have highly abnormal blood / fat samples and measurable cognitive impairment. All subsequent tests showed a clear case of chemical toxic poisoning including Tricresyl phosphate (a unique engine oil additive) being found in his fat.
It was at this time that Capt Hoyte became aware of many other pilots who had the same neurological symptoms; including one pilot who had been grounded in 2000 by the CAA due to suspected organophosphate poisoning as he was deemed to be a ‘flight safety risk’.
Like many pilots, Capt Hoyte found very little help available from his GP or NHS. He changed his GP twice after being offered anti depressants whilst exhibiting ‘symptoms of depression’ but knowing he was not a depressed type. He took no anti depressants. Any testing was hard to organise and he found little assistance from Balpa.
Capt Tristan Loraine & Capt Susan Michaelis of GCAQE would be his sole source of assistance and first suggested that he may be suffering from ‘Aerotoxic Syndrome’ in June 2006.
By early 2007 Capt Hoyte was determined to prevent any other aircrew or passengers from
enduring what he had experienced, especially as his health slowly began to recover.
He set up the Aerotoxic Association for the benefit of other aircrew and passengers in June 2007
at the UK Houses of Parliament.
As a result of not flying for over three years, Capt Hoyte's health has returned , more or less, to how it was in 1989.
